"I discarded brushes and explored the mind more than the hand."  M. Duchamp

"The poetic truth does not exist in that something has actually occurred, but rather in that it could occur, therefore in the inner possibility of the matter. The aesthetical force must therefore already lie in the conceived."  Friedrich Schiller
